How the Exploit Works
The vulnerability arises from a flaw in the system that allows an unauthorized user to download the configuration backup. The system fails to properly validate and authenticate the user before allowing access to the configuration backup. This leads to unauthorized access and potential compromise of the system. Furthermore, the system uses a hardcoded static key for encryption, which can be exploited to decrypt passwords included in the configuration backup.
Conceptual Example Code
The following is a conceptual example of how this vulnerability could be exploited:
GET /config/backup HTTP/1.1
Host: target.example.comIn the above request, an attacker could simply send a GET request to the backup endpoint of the vulnerable system. Since the system does not properly validate or authenticate the user before providing access to the configuration backup, the attacker can download it without authorization. Once the backup is obtained, the attacker can then use the hardcoded static key to decrypt any passwords included in the backup.
